FOREWORD
One of the major programmes of the IAEA Environment Laboratories is to assist Member
States in the understanding, monitoring and protection of both terrestrial and marine
environments. To assess the impact of land and sea based pollution sources on marine coastal
environments, it is imperative to ensure the quality and comparability of the analytical data
generated by national and regional pollution monitoring programmes. Since the early 1970s,
the IAEA has assisted national laboratories and regional laboratory networks through the
production of certified reference materials, training in quality assurance and evaluation of
measurement performances by organizing worldwide and regional interlaboratory comparison
exercises and proficiency tests.
This publication describes the production of certified reference material IAEA-459, which is
produced following ISO Guides 34:2009 and 35:2006. This certified reference material is a
sediment sample with certified mass fractions of polycyclic aromatic hydrocarbons,
organochlorines and polybrominated diphenyl ethers. The assigned final values and their
associated uncertainties were derived from robust statistics on the results provided by selected
laboratories with demonstrated technical and quality competence, following the guidance
given in the ISO Guides. The material is used for quality control and assessment of method
performance for a number of organic analytes listed in the Stockholm Convention on
Persistent Organic Pollutants as well as other pollutants listed as priority substances included
in many environment monitoring programmes.
The IAEA is grateful to the Government of Monaco for its support and wishes to thank all
laboratories and participants who took part in the characterization study of this reference
material, in particular the Korea Institute of Ocean Science and Technology for the donation
of the raw material. The IAEA officers responsible for this publication were I. Tolosa,
R. Cassi and D. Huertas of the IAEA Environment Laboratories.

1. INTRODUCTION
The Marine Environmental Studies Laboratory (MESL) of IAEA-EL provides assistance to
Member States’ laboratories to enhance the quality of the analytical measurement results, in
trace elements and organic contaminants in the marine environmental samples. This is
achieved through the production of certified reference materials, organization of
interlaboratory comparisons and proficiency tests, and by conducting training courses on the
analysis of contaminants in marine samples. This activity is undertaken in the framework of
the EL’s subprogramme 2.4.1 “Reference Products for Science and Trade” and the Project
2.4.1.1 “Provision of Reference Products and Assurance of Laboratory Performance”.
Certified Reference Materials (CRMs) are valuable tools for analytical method development
and validation to improve the measurements and quality control in analytical laboratories.
More specifically, marine matrix CRMs are needed to ensure the reliability of the analytical
measurements and ensure the use of high quality data as the basis for decision making in
national or regional marine pollution monitoring programmes. Furthermore, since the
Stockholm Convention (SC) on persistent organic pollutants (POPs) was adopted 15 years
ago, a great number of different analytical methodologies have been extensively developed
and there is great need of CRMs for these contaminants. While there are several CRMs
certified for organic contaminants, there is still a noticeable lack of matrix CRMs, in
particular for POPs in marine sediments, where the concentrations levels are in the low range
of µg kg-1
. To meet this need, MESL has developed a sediment CRM for the determination of
a great number of organic analytes listed as Persistent Organic Pollutants (POPs) by the
Stockholm Convention as well as other POPs listed as priority substances (PSs), such as
polycyclic aromatic hydrocarbons included in many environment monitoring programmes.
This report describes and provides information on the sample preparation methodology
followed and on the assignment of property values with their associated uncertainties for a
number of persistent organic contaminants in a marine sediment sample. Certification of the
mass fractions was made for major POPs, including polycyclic aromatic hydrocarbons
(PAHs), polychlorinated biphenyls (PCBs), chlorinated pesticides and polybrominated
diphenyl ethers (PBDEs). Results on aliphatic hydrocarbons and other minor POPs are also
provided as information values.
The CRM IAEA-459 was produced to satisfy the needs of laboratories to strengthen data
quality assurance in the analysis of POPs and other priority substances in marine samples

2. METHODOLOGY
2.1. COLLECTION AND PREPARATION OF THE MATERIAL
A sample of marine sediment was collected in Han River estuary, South Korea. This sample
was dried, ground and sieved at 125 µm. The powder obtained, about 26 kg, was
homogenized by mixing it in a stainless steel rotating drum for three weeks. Then, aliquots of
about 50 grams were packaged into cleaned amber glass bottles with aluminium screw caps,
labeled IAEA-459 and sealed with Teflon tape. This material was previously used in a
worldwide interlaboratory comparison (ILC) exercise performed in 2012, where 82
laboratories from 43 countries reported data on organochlorine compounds, polybrominated
diphenyl ethers and petroleum hydrocarbons [1].
2.2. SELECTION OF LABORATORIES FOR THE CHARACTERIZATION STUDY
The selection of participating laboratories was based on the results they have provided during
a previous ILC for the same compounds in sediment. Only laboratories that provided reliable
and satisfactory data by applying valid quality control and quality assurance procedures were
invited to participate in this characterization study.
One bottle of sediment sample was sent to each participating laboratory, accompanied by an
information sheet and a reporting form to include the data results for chlorinated pesticides,
polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), polycyclic
aromatic hydrocarbons (PAHs) and aliphatic hydrocarbons. The systematic numbering of
PCB and PBDE congeners is listed respectively in Appendixes X and XI. Six replicate
aliquots were requested to be analysed using their usual technique, and the reported results
had to be accompanied with the description of the method used together with the applied
quality control procedures, including results for the organic contaminants in a CRM with a
matrix similar to the candidate reference material.
The laboratories participating in the characterization study are listed on page 129.
2.3. HOMOGENEITY ASSESSMENT
In order to establish the degree of homogeneity of the reference material with respect to the
properties of interest, both within- and between-unit homogeneity have to be evaluated to
ensure that all distributed units are the same within the stated uncertainty [2].
Homogeneity test was performed by MESL after the bottling of the sample material. The
between bottle homogeneity of the material was assessed by determining the concentration of
selected organochlorine pesticides, polychlorinated biphenyls, polybrominated diphenyl
![Page 12: IAEA Analytical Quality in Nuclear Applications Series No ... · ISSN 2074–7659 Template has: 20 mm spine please reset it to the corrected spine/ ... KYRGYZSTAN LAO PEOPLE’S DEMOCRATIC](https://reader033.vdocument.in/reader033/viewer/2022060901/609e4a569bb2a56d242d577a/html5/thumbnails/12.jpg)

ethers and petroleum hydrocarbons in sample aliquots of 6 g taken from 10 bottles (about 3%
of the total batch) randomly selected during the whole bottling process of the bulk dry
powder. Each bottle unit was extracted and analysed without subsampling. Homogeneity
assessment based on the analysis of variance (ANOVA) to calculate between-unit variation
(sbb) and within bottle heterogeneity (swb) could therefore not be applied [2], but the ANOVA-
like approach [3, 4] was followed. The within-bottle homogeneity of the material was
assessed by determinations of the concentration of organochlorine (OC) pesticides,
polychlorinated biphenyls, polybrominated diphenyl ethers and petroleum hydrocarbons in six
sample aliquots of 6 g taken from 1 bottle. The same method of analysis was used to test the
between-bottle and within-bottle homogeneity. Samples were run in a random order to avoid
the instrumental analysis sequence following the same order of preparation.
2.4. STABILITY STUDY
Stability information is important to determine the presence of any potential degradation of
the analytes during sample transport to the customers (short-term stability) as well as
conditions for storage (long-term stability) of the material. Time, temperature, moisture and
radiation are usually the more pertinent parameters affecting stability of the samples. The
influence of light was minimized by using amber bottles, which were stored in the dark and
moisture was minimized by the drying preparation of the material. Consequently, only the
influence of time and temperature were investigated by using an isochronous stability design.
To test stability, selected units are exposed to different storage conditions during different
periods of time. Then, the units are transferred to conditions where additional potential
degradation is considered extremely unlikely (reference conditions). At the end of the
isochronous storage, the units are measured under repeatability conditions in a single run,
providing the best available precision for the stability study.
2.4.1. Short-term stability
The approach used to assess the transportation stability was based on an isochronous design
over 4 weeks. For that, a set of 4 units were stored in the dark at +20°C immediately after the
bottling and another set of 4 bottles at +40°C for 1, 2, 3 and 4 weeks respectively. After the
planned exposure time for each unit, were moved to reference conditions (-20°C temperature).
One independent measurement per bottle was performed under repeatability conditions. The
obtained results were compared with the results from samples kept at -20°C from the time
zero of this study. The tests were performed by measuring phenanthrene, fluoranthene, pyrene
by GC-MS and PCB 138, PCB 153, pp’-DDE and BDE-99 by GC-ECD. All measurements
were performed under repeatability conditions, with the purpose to improve the measurement
precision and consequently the power of the isochronous stability study.

2.5. CHARACTERIZATION
Characterization refers to the process of assigning a property value that can be reliably
assessed when its value is confirmed by several laboratories working independently and using
different methods, for each of which the accuracy has been well established [5]. The material
was initially analysed in the IAEA/NAEL in Monaco. The final characterization was based on
the results provided by selected laboratories with demonstrated technical and quality
competence
The characterization of the PAHs was performed by using three different analytical
techniques: gas chromatography/mass spectrometry (GC-MS), gas chromatography/high
resolution mass spectrometry (GC-HRMS) and high performance liquid
chromatography/fluorescence detector (HPLC–FLD) as summarized in Figure 1.
Fig. 1. Analytical methods used for the characterization of PAHs in the IAEA-459 sediment
sample. Abbreviations used to describe the instrumental techniques are given in Table 1.
The characterization of the PCBs was based on the application of five different analytical
techniques: two-dimensional gas chromatography/electron capture detector (GCxGC-ECD),
gas chromatography coupled to tandem mass spectrometry (GC-MS/MS), GC-MS, GC-
HRMS and gas chromatography/electron capture detector (GC-ECD) as summarized in
Figure 2.

The characterization of the PBDEs was based on the application of four different analytical
techniques: gas chromatography/mass spectrometry by electron impact (GC-MS-EI), gas
chromatography/mass spectrometry by negative ion chemical ionization (GC-MS-NICI), GC-
HRMS and GC-ECD as summarized in Figure 4.

respectively 10, 12 and 7. The basic principles for evaluation of measurement uncertainty
were followed according to the ISO Guide 35 [2] and the Guide to the Expression of
Uncertainty in Measurement (GUM) [6], which combines the different uncertainties of
characterization, inhomogeneity and instability.
2.6. MOISTURE CONTENT
The moisture content of the lyophilized material, determined by drying an aliquot to a
constant mass at 105°C, was found to be 1.7±0.1 % at the time of the preparation of this
sample and 2.8 ±0.1% at the time of this characterization exercise.
2.7. ELEMENTAL COMPOSITION AND ISOTOPES VALUES
Total carbon and nitrogen percent composition as well as carbon and nitrogen isotopic
composition (δ13
C and δ15
N) were measured on a Thermo Fisher Flash 2000 elemental
analyzer coupled to a Delta V Advantage isotope ratio mass spectrometer. The values are
shown in Table 2.

3.RESULTS AND DISCUSSION
3.1. RESULTS OF THE HOMOGENEITY STUDY
3.1.1. Between-unit homogeneity
To assess the uncertainty related to the inhomogeneity, 10 bottle units (about 3% of the total
batch) of sediment samples were selected by using a random stratified sample picking scheme
and analysed for their organic contaminants under repeatability conditions. Each bottle unit
was extracted and analysed without subsampling. Homogeneity assessment based on the
analysis of variance (ANOVA) to calculate between-unit variation (sbb) and within-bottle
heterogeneity (swb) could therefore not be applied [2], but the ANOVA-like approach was
applied, according to Linsinger et al , 2001 [3] and Van der Veen et al., 2001 [4], as shown in

where uc,bb is the combined uncertainty of the between-unit experiment, expressed as the
uncertainty on a single unit; sbb is the variation between units and smeas is the intrinsic
variability of the method (smethod) divided by the square root of n, the number of replicates per
unit; sbb is the estimate of between-bottle variation in the material, named uhom.
Tables 3, 4 and 5 summarize the estimates of inhomogeneity contributions to the total
uncertainty and the number of outliers at 95% and 99% confidence levels by using Grubbs
tests. Only outliers at 99% confidence level were removed for the statistical analysis.

The coefficient of variation for the content of the major analytes between the 10 different
sample bottles was below 10%. Thus the material was considered sufficiently homogeneous
for the parent PAHs, the organochlorinated and PBDEs compounds at 6 g sample size. The
uncertainty of inhomogeneity for alkylated PAHs not included in the homogeneity study was
set at the same percentage as their respective parent PAH compounds; for the PBDEs not
included in the homogeneity study was set at the same percentage as the selected PBDEs
(BDE 47 and BDE 99).
3.1.2. Within-unit homogeneity
For within-bottle homogeneity studies, a similar approach as between-unit homogeneity
might be developed, but the intrinsic variability of the method (smethod) can not be determined
independently because a similar material with perfect within-unit homogeneity does not exist
[4]. In this respect, we can assume that the within-bottle homogeneity can be set to the
intrinsic variability of the method (smeas) which is shown in Tables 3, 4 and 5. This variability
was measured by using a sample size of 6 g. However, to assess the minimum sample intake
that is representative for the entire unit and can be used in the analysis of the target
compounds, we used the method information provided by the laboratories contributing to this
characterization study. We set the minimum sample intake as the lowest sample intake that
provided data results within the accepted assigned values and stated uncertainty. In this study,
they were set at 3 g, 1 g and 2 g, respectively for PAHs, OCs and PBDEs. However, taking in
account the low concentration levels of the target analytes, we recommend a minimum sample
size of 3 g for all families of POPs.

3.2. RESULTS FOR STABILITY STUDY
3.2.1. Short-term stability study
The samples selected for short-term stability study were analysed and selected organic
contaminants (phenanthrene, fluoranthene, pyrene, PCB 138, PCB 153, pp’-DDE and BDE-
99) were evaluated individually for each temperature (20°C and 40°C). Measurements were
performed under repeatability conditions and linear regression lines were calculated for each
selected analyte and tested for significance on a 95% confidence level using a Student t-test
for slope significantly different from zero. No slope associated with any of the linearity plots
generated for each selected analyte was detected that differed significantly from zero. As
results did not show any significant trend of degradation over the timeframe at different
temperatures +20°C and +40°C, no special precautions regarding temperature control during
transport are needed. These results are supported by the chemical nature of the persistent
organic contaminants which owe a high chemical stability and persistence. Therefore, no
additional uncertainty with respect to instability due to transport needs to be taken into
account and the uncertainty associated with short-term stability under transport conditions is
taken as zero.
3.2.2. Long-term stability study
Long-term stability evaluation aims to determine if the certified values of the analyte(s)
remain valid during the 5 to 10 year lifetime of the certified reference material. Based on
experience with similar materials issued by the IAEA and statements of expiry dates on
certificates of other CRM providers such as NIST, the material is expected to be stable for 5-
10 years, provided that it will be stored in the dark at temperatures below 30°C [7, 8].
As no measurements on instability was determined over long term storage conditions, the
uncertainty for long-term stability was set as the intrinsic variability of the method smeas, which
is shown in Tables 3 for PAHs and Tables 4 and 5 for PCBs, OCs and PBDEs. The long-term
stability test will be monitored at regular intervals and changes, which may occur, will be
reflected in an updated certificate of analysis provided to the users.
3.3. DETERMINATION OF ASSIGNED VALUES AND UNCERTAINTIES
The determination of the assigned values and its standard uncertainty for organic
contaminants in the IAEA-459 sample were derived using the robust statistics approach,
which provide high resistance to the influence of extreme outlying values [2]. The robust
values of the average and standard deviation of the data was calculated using the Algorithm A
provided in the Annex C.1 from the ISO standard 13528 [9].
First, the set of p individual results were ranked in increasing order by (x1, x2, xi,…, xp). Then,
the median x* of the data was calculated as:
![Page 21: IAEA Analytical Quality in Nuclear Applications Series No ... · ISSN 2074–7659 Template has: 20 mm spine please reset it to the corrected spine/ ... KYRGYZSTAN LAO PEOPLE’S DEMOCRATIC](https://reader033.vdocument.in/reader033/viewer/2022060901/609e4a569bb2a56d242d577a/html5/thumbnails/21.jpg)
12
�∗ = median of��(i=1,2,3….p) (3)
The robust standard deviation of the data set was calculated:
�∗ = 1.483 ×median|�� − �∗|(i=1,2,3…..p) (4)
The final “cut-off” values used in the robust algorithm was estimated as:
� = 1.5 × �∗ (5)
For each xi, it was calculated:
��∗ = ���∗ = �∗ − �,if�� < �∗ − ���∗ = �∗ + �,if�� > �∗ + ���∗ = �∗,otherwise � (6)
New values for the robust mean x* and �∗ were updated as follows:
�∗ = ∑ � ∗!"# (7)s∗ = 1.134$%&'(∗)'∗*+&,)-* (8)
where the summation is over i
The robust estimates �∗ and �∗ were derived by an iterative calculation by updating the
values of x* and s* several times using the modified data, until the process converged to the
third significant figure of the robust standard deviation and robust average.
These estimate values were similar to other robust estimates of the mean calculated with the
algorithms offered by the Analytical Methods Committee of the Royal Society of Chemistry
(AMC) [10, 11].
The uncertainties associated with the assigned property values were conducted according to
ISO Guide 35 [2]. The relative combined uncertainty of the assigned property value of the
CRM involved combining the standard uncertainties associated with the characterization
(uchar), homogeneity (uhom), short term stability (ushort) and long-term stability (ustab). Because
the uncertainty component derived from the short term stability was insignificant and
assumed to be zero, the final expanded uncertainty was a combination of the other three
different contributions using the law of propagation of uncertainty as shown in Eq. 9:
. = / × 0�1234� + �5637� + �289� (9)

Where k is the coverage factor of 2, representing a confidence level of 95%
uhom was calculated as described in section 3.1.1.
ustab was calculated as described in section 3.2.2.
uchar was calculated as described in ISO 13528 [8] using Eq. 10:
�1234 = 1.25 × 5∗√# (10)
Where: s* is the robust standard deviation calculated from Eq. 8 and p is the number of
participating laboratories.
The final assigned values derived by robust mean are shown in Tables 6, 7, 8 and 9 together
with their individual and final uncertainty budget.

The robust mean of the laboratory means were assigned as certified values, for those
compounds where the assigned value was derived from at least five datasets and its relative
expanded uncertainty was less than 40 % of the assigned value. The certified values for 18
PAHs, 22 PCBs, 6 organochlorinated pesticides and 5 PBDEs are summarized in Tables 10,
11, 12 and 13 together with their expanded uncertainty. For all these compounds, the values
were derived from at least 3 different analytical techniques excepting, dibenzothiophene,
benzo(e)pyrene, Chrysene+triphenylene, and Benzo(b+j)fluoranthene which were derived
from two analytical techniques. Mass fractions of compounds that did not fulfill the criteria
of certification are considered information values. Tables 14, 15, 16 and 17 shows the
information values for 29 PAHs, 11 PCBs, 16 organochlorinated pesticides and 5 PBDEs
together with the expanded uncertainty for the compounds that could be calculated. Appendix
IX also shows some few datasets of aliphatic hydrocarbons for information values.

4. METROLOGICAL TRACEABILITY AND COMMUTABILITY
Metrological traceability is defined as the property of a measurement result where the result is
related to a reference through a documented unbroken chain of calibrations, each contributing
to the measurement uncertainty [10]. The methods used by all participating laboratories were
validated by using matrix standard reference materials (CRMs) from NIST (SRM1941b, SRM
1944), IAEA (IAEA-408, IAEA-159) and materials characterized by QUASIMEME
proficiency tests (MS3 polycyclic aromatic hydrocarbons in sediment, MS2 chlorinated
organics in sediment). The fact, that values reported by participants are based on calibration
standard solutions of known purity, issued by accredited commercial companies with
documented unbroken chain of calibrations, demonstrates that the assigned values derived
from combining the individual results are traceable to International System of Unis (SI).
Furthermore, the agreement between the results generated by different analytical
methodologies ensures the comparability of the measurement results and validates the identity
of the measurand.
Commutability is a property of an RM, demonstrated by the closeness of agreement between
the relation among the measurement results for a stated quantity in this material, obtained
according to two given measurement procedures, and the relation obtained among the
measurement results for other specified materials [5].
A material is said to be commutable when the measurand in the routine test samples behaves
similar as in the CRM with respect to the different measurement procedures. This implies that
the application of the procedures to the CRM would produce the same quantitative value as
normal routine samples containing the same concentration of the measurand. In this respect,
IAEA-459 is a natural marine sediment sample and their analytical behaviour should be the
same as for a routine sample of dried sediment samples. The agreement between the data
acquired with different analytical procedures for the IAEA-459 characterization study
endorses the absence of any significant method bias and shows commutability of the material
for all certified organic compounds.
5. CONCLUSIONS
Combination of different data sets from at least two different analytical techniques has
allowed the assignment of certified concentrations for 22 PCBs, 6 OC pesticides, 5 PBDEs

and 18 PAHs following the recommendation of ISO Guide 35. The extensive characterization
at very low concentration levels and associated uncertainties will make CRM 459 a valuable
sediment reference material for use in the validation of analytical methods for the
determination of a great number of persistent organic contaminants listed at the Stockholm
Convention as well as other persistent and priority substances (PSs), such as polycyclic
aromatic hydrocarbons included within the environmental monitoring programs.
